Patent number: 6261563Abstract: The present invention provides recombinant DNA molecules comprising a sequence encoding a pseudorabies virus (PRV) glycoprotein selected from the group consisting of gI, gp50 and gp63 host cells transformed by said recombinant DNA molecule sequences, the gI, gp50 and gp63 polypeptides. The present invention also provides subunit vaccines for PRV, methods for protecting animals against PRV infection and methods for distinguishing between infected and vaccinated animals.Type: GrantFiled: June 7, 1995Date of Patent: July 17, 2001Assignee: Pharmacia & Upjohn CompanyInventors: Erik Aivars Petrovskis, Leonard Edwin Post, James G. Timmins

Patent number: 6084073Abstract: DNA sequences encoding full length precursor proteins, which proteins contain both A and B portions of two ricin isotoxins and ricin agglutinin, as well as the linker regions have been determined. These DNAs or portions or modifications thereof are expressed in recombinant hosts to obtain the desired proteins or proteins which can readily converted thereto. One of the ricin isotoxins may be related to ricin E.Type: GrantFiled: June 5, 1995Date of Patent: July 4, 2000Assignee: Chiron CorporationInventor: Michael Piatak, Jr.

Patent number: 5723120Abstract: This invention provides a class of interleukin-6 (IL-6) muteins which act as IL-6 receptor antagonists, thereby inhibiting the normal function of naturally-occurring IL-6. These IL-6 receptor antagonism are preferably IL-6 molecules containing one or more mutations in the Site II region comprising amino acids 154-163. This invention also provides pharmaceutical compositions comprising IL-6 receptor antagonists with a pharmaceutically acceptable carrier. This invention further provides methods for treating IL-6 related diseases such as sepsis and multiple myeloma, the methods comprising administering to a patient an IL-6 receptor antagonist.Type: GrantFiled: June 7, 1995Date of Patent: March 3, 1998Assignees: Chiron Corporation, Central Laboratory of the Netherlands Red Cross Blood Transfusion ServiceInventors: Just P. J. Brakenhoff, Lucien A. Aarden

Patent number: 5538868Abstract: Recombinant vectors and methods for constructing ricin B are disclosed. The coding sequence for ricin B was cloned, disposed in suitable expression vectors and produced free of components normally accompanying this peptide. In addition, a novel means of reconstructing missing portions of coding sequence, and certain improvements in messenger RNA purification are disclosed.Type: GrantFiled: January 23, 1995Date of Patent: July 23, 1996Assignee: Cetus Oncology CorporationInventors: Glenn T. Horn, Michael Piatak, Jr.
